One option is to manually edit (using vi) /config/bigip_base.conf, and change both your self IP and floating self IP masks. Then reload the config with 'tmsh load sys config'

 

Just labbed this out and worked like a champ.

    Perfect thank you...just implemented on non-prod and prod ltms.(11.4) As you said worked like a champ. But for some reason need to do this on active device first. Not Stby - including self ip. If I changed the self ip on Stby first it would revert back.
